This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Basically the same as G_LROUND. Handles the llvm.llround family of intrinsics. Also add a helper function to the MachineVerifier for checking if all of the (virtual register) operands of an instruction are scalars. Seems like a useful thing to have.
